Interesting rat hole(s) and good information. Turns out I don't need g_ether on the Scientific Linux side. it *looks* like a hotplug event is supposed to load a driver to create and interface usb0. More digging is required. Thanks for your attention! BTW, if someone knows the module that's supposed to load... It'd save me some time, but I can dig more too.
